Friend got ridiculed for wearing a mask

Given the increasing discovery that there are many asymptomatic carriers of C-19 the chances that non mask wearing people may be carrying the virus unknowingly and spreading it to others as well as high risk people speaks all the more as to why masks should be worn by all in public places. NH peak is predicted to occur in mid to late May. Why? As more people are exposed from unknowing carriers the more will show up sick at the hospitals in about two weeks after exposure.
Now I am in CA. in a town outside of Los Angeles. Population about 32,000. Number of known cases to date 20 and holding. Mask wearing compliance is 98% and now required by all store workers and patrons.
When I arrive next week in NH I will be wearing a mask whenever I am out after my 14 day quarantine period. Why, not because I may be infected, but I am more concerned about getting infected by people who do not believe they can get sick.
